如何以编程方式在我的EditText上设置焦点(并显示键盘)

我有一个包含如下视图的布局:

<LinearLayout>
<TextView...>
<TextView...>
<ImageView ...>
<EditText...>
<Button...>
</linearLayout>

如何以编程方式在我的EditText上设置焦点(显示键盘)?

我已经尝试过了，它只在我正常启动我的活动时才起作用，但当我在TabHost中启动它时，它不起作用。

txtSearch.setFocusableInTouchMode(true);
txtSearch.setFocusable(true);
txtSearch.requestFocus();

当前回答

这对我很有效，多亏了ungalcrys

显示键盘:

editText = (EditText)findViewById(R.id.myTextViewId);
editText.requestFocus();
InputMethodManager imm = (InputMethodManager)getSystemService(this.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,InputMethodManager.HIDE_IMPLICIT_ONLY);

隐藏键盘:

InputMethodManager imm = (InputMethodManager) getSystemService(this.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);

试试这个:

EditText editText = (EditText) findViewById(R.id.myTextViewId);
editText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

showSoftInput根本不为我工作。

我想我需要设置输入模式:android:windowSoftInputMode=" statevvisible "(在这里的活动组件在清单)

希望这对你有所帮助!

这里是KeyboardHelper类，用于隐藏和显示键盘

import android.content.Context;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;

public class KeyboardHelper {
public static void hideSoftKeyboard(final Context context, final View view) {
    if (context == null) {
        return;
    }
    view.requestFocus();
    view.postDelayed(new Runnable() {
        @Override
        public void run() {
            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null;
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}, 1000);
}

public static void hideSoftKeyboard(final Context context, final EditText editText) {
    editText.requestFocus();
    editText.postDelayed(new Runnable() {
        @Override
        public void run() {
            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null;
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
}
}, 1000);
}


public static void openSoftKeyboard(final Context context, final EditText editText) {
    editText.requestFocus();
    editText.postDelayed(new Runnable() {
        @Override
        public void run() {
            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null;
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
}
}, 1000);
}
}

final EditText tb = new EditText(this);
tb.requestFocus();
tb.postDelayed(new Runnable() {
    @Override
    public void run() {
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        inputMethodManager.showSoftInput(tb, InputMethodManager.SHOW_IMPLICIT);
    }
}, 1000);

use:

editText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
