在我的应用程序中,我有10个Edittext和10个TextView
我已经为EditText和TextView创建了实例
String[] messageText=new String[10];
String[] messageEdit=new String[10];
TextView oTextView1 = (TextView) findViewById(R.id.Tab_common1_EditText);
TextView oTextView2 = (TextView) findViewById(R.id.Tab_common2_EditText);
TextView oTextView3 = (TextView) findViewById(R.id.Tab_common3_EditText);
TextView oTextView4 = (TextView) findViewById(R.id.Tab_common4_EditText);
TextView oTextView5 = (TextView) findViewById(R.id.Tab_common5_EditText);
TextView oTextView6 = (TextView) findViewById(R.id.Tab_common6_EditText);
TextView oTextView7 = (TextView) findViewById(R.id.Tab_common7_EditText);
TextView oTextView8 = (TextView) findViewById(R.id.Tab_common8_EditText);
TextView oTextView9 = (TextView) findViewById(R.id.Tab_common9_EditText);
TextView oTextView10 = (TextView) findViewById(R.id.Tab_common10_EditText);
EditText oEditTextHiden1 = (EditText) findViewById(R.id.Tab_Hidencommon1_EditText);
EditText oEditTextHiden2 = (EditText) findViewById(R.id.Tab_Hidencommon2_EditText);
EditText oEditTextHiden3 = (EditText) findViewById(R.id.Tab_Hidencommon3_EditText);
EditText oEditTextHiden4 = (EditText) findViewById(R.id.Tab_Hidencommon4_EditText);
EditText oEditTextHiden5 …我有一个EditText和一个CountDownTimer.通常,如果你使用EditText启动一个Activity,EditText会激活并显示键盘.但我希望Activity启动,计时器关闭,然后键盘自动显示.我怎样才能做到这一点？
new CountDownTimer(5000, 1000) {
public void onTick(long millisUntilFinished) {
//Do Something
}
public void onFinish() {
//Keyboard pop up
}
}.start();
我有一个EditText,允许用户从默认的起始位置输入文本.我想将光标从起始位置移开并将其设置为距起始位置约6 dp.我怎样才能做到这一点？
我很抱歉,如果我做了任何愚蠢的错误,但我找不到这个的来源:我试图在我的EditText"etItem"上实现一个onDrag监听器这是我的代码:
etItem.setOnDragListener(new OnDragListener(){
@Override
public boolean onDrag(View v, DragEvent dragevent) {
if(null!=dragevent && null!=v){
if( dragevent.getAction() == DragEvent.ACTION_DROP )
{
View view = (View) dragevent.getLocalState();
ViewGroup owner = (ViewGroup) view.getParent();
int itemNum = (Integer) view.getTag();
itemAmounts[itemNum] = 0;
owner.removeView(view);
return true;
}
}
return false;
}});
这在我的Samsng Galaxy Grand上工作得很好,但是在Nexus上给了我一个nullpointer.

<EditText
android:id="@+id/editText3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView4"
android:layout_alignParentRight="true"
android:layout_below="@+id/textView4"
android:layout_marginTop="28dp"
android:inputType="textCapSentences"
android:ems="10"
android:inputType="textMultiLine" /> // cannot add this here
我按照答案尝试但是多行工作正在运行,但init cap在这个edittext和写的那些文件中都不起作用
android:inputType="textCapSentences"
:-(
在我的应用程序中,我有搜索选项卡,在网格视图中显示带有其名称的图像,现在我想实现搜索功能.我一直在谷歌搜索过去两天,但我没有得到任何解决方案.任何想法或教程0r我怎样才能实现这一目标？
有人帮我这个.
提前致谢.

我目前正在做的是获取字符数,如果它超过特定限制,减少字体大小.我想要做的是当滚动选项被激活时,需要减小大小.
qQuestionEditText.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
// TODO Auto-generated method stub
qCount.setText(String.valueOf(200 - s.length()));
if (qQuestionEditText.length() > 180) {
qQuestionEditText.setTextSize(20);
} else if (qQuestionEditText.length() > 150) {
qQuestionEditText.setTextSize(22);

qQuestionEditText.setTextSize(24);

qQuestionEditText.setTextSize(30);

@Override
public void …我在MyEditText类中重写了这个方法:
@Override
public Editable getText() {
Editable s = (Editable) super.getText();
s.toString().replace("$", "").trim();
return s;
}
MainActivity类是:
public class MainActivity extends Activity implements OnClickListener {
MyEditText myEditText;
Button btn;
TextView tv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.try_layout);
myEditText = new MyEditText(this);
btn = (Button) findViewById(R.id.btn);
tv = (TextView) findViewById(R.id.tv);
btn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
tv.setText(myEditText.getText().toString());
}
}
当我在edittext中输入一些值然后点击btn没有任何文本从edittext获取为什么.
使用Kitkat但也尝试使用jellybean并且我无法获得自定义错误图标.
我从Android doc使用这两个重载方法来设置setError(...)
我只是做了非常简单的代码:
import android.app.Activity;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.RadioGroup;
import android.widget.RadioGroup.OnCheckedChangeListener;
public class MainActivity extends Activity implements OnCheckedChangeListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.report_issue);
RadioGroup rg = (RadioGroup) findViewById(R.id.myradio_group);
rg.setOnCheckedChangeListener(this);
}
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (checkedId == R.id.radio_two) {
EditText et = (EditText) findViewById(R.id.et_city);
// rb.setError("i got a single error");
et.setError("my error",
getResources().getDrawable(R.drawable.ic_launcher));
//as you can see from above im setting …
